Highest-density network application card

The Cisco Nexus® V9P and V9P-3 FPGA Application SmartNIC is an FPGA (Field Programmable Gate Array) based network application card, optimized for low latency and high density.

The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters are equipped with a powerful 16nm Xilinx Virtex UltraScale Plus (VU9P) FPGA with 2.5M logic cells, into a compact, half-height, half-length, PCIe 16x form factor.

High-capacity and low-latency memory

An extensive memory hierarchy for complex, memory-intensive applications.

The Xilinx VU9P FPGA features 75Mbit of block RAM and 270Mbit of UltraRAM on chip. The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters are also equipped with an additional 9GB of DDR4 DRAM on the board for high throughput access. The DRAM is accessible via a 72-bit-wide bus for maximum performance.

The Cisco Nexus V9P-3 FPGA Application SmartNIC model performs at a higher speed reducing the compile time by 40% over the V9P model compile times, that reduces project build time while increasing network uptime. The improved V9P-3 model logic performance and the faster clocked FPGA helps to eliminate any timing issues and can be programmed to reduce network latency to create a better user experience.

High-bandwidth connectivity

Dual QSFP-DD ports provide up to 400Gbps of full duplex connectivity.

The dual QSFP-DD ports offer high-speed 4x40GbE or 2x200GbE connectivity. Using QSFP-DD breakout cables expands the connectivity to 16x10GbE/25GbE4 connections. This high-density connectivity enables a range of high-performance, directly connected network applications, bypassing the need for traditional switching and multiplexing requirements.

Extensive IP library

Cisco is a specialist in low-latency, high-performance FPGA IP cores.

We provide you the same high-speed, low-latency IP blocks used in our market leading products, including:

      10GbE PCS/MAC with ultra-low-latency performance

      Low-latency, high-throughput PCIe DMA engine

      Timing, signaling, and register interfaces, including I2C

      Packet field extractor and frame multiplexer (with source code)

      Asynchronous FIFO and CDC modules (with source code)

Several example designs are also provided to help get design work started and completed quickly.

Integrated software library

A standard Linux driver as well as transparent TCP and UDP acceleration and low-level packet access.

The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters function out of the box as a high-performance network adapter. The entire Cisco Nexus SmartNIC software library is available, including the ExaSOCK sockets application acceleration system and the libexanic direct user-space access API. Libexanic provides easy support for low-latency packet TX/RX, managing the FPGA state (through register access), and low-latency TCP/UDP delegated sending of operations for hybrid hardware/software applications. The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters also support fast and easy firmware updates (without requiring reboots) and vital statistics monitoring (temperatures, light levels, etc.).
